In this blog I want to introduce you to the concept of signing Docker images. Signing your docker images will add some layer of trust to your images. This can guarantee a consumer of your image that this image is for sure published by you and hasn’t been tampered with by others. You might already used PGP to sign your Git commits. In this blogpost I shown a nice way of setting PGP signing keys using Krypton that adds 2FA. In practice Docker image signing is the same concept. If this all sounds a bit fuzzy to you, please continue reading, hopefully I am able to make things more clear. ;-)
I see many struggle when it comes to using Secure Shell in a comfortable way. Many are installing unneeded applications like Putty on Windows for example. Just like I did 4 years ago. Over the years I have been working a lot on servers where there was no GUI available and learned a lot doing that. I would like to share my tips and tricks so you can also be empowered by just sticking to the terminal on your OS or simply using Git Bash on Windows.
In this blog I will cover how I’m managing and versioning the tools my Go projects depend on. Go Modules are available since Go 1.11. Using Go Modules you can manage the dependencies for your project. You can compare it to NPM in Nodejs projects or Maven in Java project or Nuget in .NET projects.
In the previous blog of this series I explained the basics of getting a fresh installation of Raspbian on your Rapberry Pi including SSH access and configuration of a static IP for your Wifi. In this
In my last blog I shown you how to upgrade from Raspbian Stretch to Raspbian Buster. As the whole upgrade went smooth it seems there are still some issues with Raspbian Buster. The one which blocked m
In a previous blogpost I wrote how to create a Webserver in Go with graceful shutdown. This time I want to show you a more improved version which you can utilize better in your projects as it can be used as a drop in server.go file in your project where I also make use of some popular high performing libraries.
In this blogpost I want to show you how you can make a http webserver in Go with gracefull shutdown. Using this approach you allow the server to clean up some resources before it actually shuts down. Think about finishing a database transaction or some other long operation. We will be using the things we learned in my blogpost on concurency. So expect to see channels and go routines as part of the solution.
In this blog I would like to zoom in on Interfaces and type assertions in Go. Compared to language like c# and Java implementing interfaces works slightly different. In the remainder of this blog I want to give you a bit of theory and practical usecases. In case this is your first time working with Go you might want to check out this blog which shows you how to setup your development environment including a small hello world.
